Setup
The auto-fill shut off (V) is used to refill the grease tank
(K) in an automatic lubrication system. When the grease
level in the tank is full, the auto-fill shut off automatically
ends the filling operation.
Always fill the tank (K) to full during refilling.
As grease is added to the tank (K), the follower plate (Y)
is pushed to the top of the tank (K) and pushes up the
valve pin (V1) which closes the inlet fluid path. Pin (V2)
pops up when the tank is full (F

When the fluid refilling path closes, the refilling line (GG)
pressurizes and brings the remote fill station pump (AA)
to a pressurized stall condition.
Note: The operator must monitor the system during fill-
ing of the tank to prevent any accidental fluid overflow.
Refill the Tank: Pumps with an Auto-fill
Shut Off (AFSO)
The breather (J) vents the tank to the atmosphere. If it
is plugged the tank will over-pressurize and rupture,
potentially causing serious injury. Be sure the
breather is not plugged before filling the pump.
